Annie -
Congrats on the new TM! I know you will love it. As you are getting acquainted, you will find that many of the common topics and questions are addressed in the
TM Technical Library which is part of this Forum. It is worth scrolling through, just to see what is there. It starts here.

As for garage door height, if your door opening is just shy of 8 feet, you are in great shape. The height of a closed TM is listed as 82 inches - just under 7 feet. Many owners (like me) have garage door opening height that is only about 84 inches. For them, there is a topic in the Library that may be useful. See post 17 here
